如何在应用程序打开(前景)时显示推送通知,当 OnMessage 被触发时?

How to show a push-notification when the application is open(foreground), when OnMessage is triggered?

我使用 Flutter 和 Firebase 消息传递。 我在示例中配置 Firebase:
firebaseMessaging.configure( onMessage: ... onLaunch: ... onResume: ... )
但我想即使在应用程序打开时也能看到推送通知。
粗略地说 onMessage 应该像 onResume 一样工作。
我该怎么做?

  onMessage: (Map<String, dynamic> message) async {
        showNotification(message);
        print('on message $message');
      }




  showNotification(Map<String, dynamic> msg) async {
    var android = new AndroidNotificationDetails(
      'your channel id',//channel id
      "your channel name",//channel name
      "your channel description",//channel desc todo set all this right
      icon: 'mipmap/launcher_icon'//add your icon here
    );
    var iOS = new IOSNotificationDetails();
    var platform = new NotificationDetails(android, iOS);


    await flutterLocalNotificationsPlugin
        .show(0, msg['notification']['title'], msg['notification']['body'], platform);


  }

我使用 flutter_local_notifications: ^1.2.2 显示本地通知前景。

此外,如果您要为 IOS 实施,请不要忘记请求通知许可。
